The Existence Of Life And Energy

Energy can be divided into different parts of our everyday life's ( Home, transportation, industry …)

Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.

Many scientists during the mid-eighteen hundreds came up with the idea of the conservation of energy and it wasn’t till the early nineteenth century when scientist became interested in the relationships between the different forces of nature. The reason for their curiosity was to create a perpetual motion engine. Many designs were created and many clamed their device would work but none truly succeeded. Lazar Carnot decided to study the relationship between a water wheel and the amount of work it produced. His son, Sadi Carnot, interested in the productive motive force, began studying the steam engine. He believed that understanding the steam engine he would be able to better understand the heat engine giving him the ability to create a more efficient engine. After studying the steam engine he suggested that caloric were being transferred by means of the steam. This was an astonishing discovery because he believed that the caloric was conserved and not consumed just like the water in the water wheel his father studied. The water was not being consumed but just falling from one level to the next similar to the caloric it was just falling from one temperature to a lower temperature. The next discovery came for Hans Christian Oersted, who was a Danish physicist. He accidentally discovered that when a wire carrying a current of electricity was next

Wind energy, one of the oldest forms of renewable energy used by humans, is produced simply by harnessing the power of the wind with wind turbines and generating electricity. Geothermal energy is energy from the heat of the Earth, and is drawn from locations with naturally heated water like hot water reservoirs and geysers or areas deep within the Earth accessed by drilling (NREL, "Learning About Renewable Energy"). Hydroelectric power, in simplest terms, uses the power of water rushing downwards to rotate a propeller attached to a generator that in turn produces electricity (Perlman). Another form of renewable energy is biomass, such as wood, biofuel, and bio-waste, which is burned to produce energy; however, it is not clean energy.

In every developed country electrical power has evolved from a luxury to an absolute necessity. Even though it is wonderful to be able to read a book using the light emitted from a lamp and people could easily use a candle. Now a more important application such as the ability to save lives using advanced medical equipment would be far too great of a loss, if were to go without power. So how do people continue to create and harness electrical energy? The large majority of electrical power comes from fossil fired or nuclear fired generation. Both fossil and nuclear fired use their fuel source to heat water into steam which is used to spin turbine of a generator. However one of the glaring weaknesses of these types of generation archetypes is

Energy is the capacity of a physical system to perform work. If there is no energy, then all systems as we know will not work. Americans rely on energy to heat their homes, charge their phone, and cook their food. The United States of America is highly dependable on a source of energy that has the ability to become depleted. Coal, oil, and natural gas are the prime resources used in creating energy, all of which are fossil fuels. Not only can fossil fuels deplete but when burned they leave a harmful carbon dioxide emission which can penetrate the earth’s ozone layer, resulting in environmental dilemmas. Renewable energy such as wind, solar, geothermal, and biomass provides advantages for our health, climate, and economy.

There are six different types of energy: Kinetic, thermal, electromagnetic, chemical potential, spring potential and gravitational potential. Kinetic energy is the energy of movement. Thermal energy is kinetic, only on a molecular level. As molecules speed up, they become warmer. Electromagnetic energy is energy in waves, for example light or microwaves. Chemical potential energy is energy stored in chemical bonds, which break when it is released. Spring potential energy is energy stored in any type of spring. Lastly, gravitational potential energy is energy gathered in an object as it moves further away from the force of gravity. None of these forms of energy are ever created or destroyed, they only change forms. One example of gathering this energy is photosynthesis. Plants gather energy from the sun using photosynthesis. During cellular respiration energy is released in a form usable for actions the cell requires. Energy relates to evolution because the ways of transformation of energy have changed. For example the chloroplasts are specialized cells to collect energy from the sun, they evolved from the simple prokaryotic

Fossil fuels are finite resources and once those are used up we need a way to continue living regularly, as our lives are built upon the ability to harness energy and produce electricity. As technology increases, alternative types of energy have become more and more enticing. Renewable energy is a very controversial topic today and has been around since the industrial revolution. Prior to the Revolution, which started in Britain in the late 1700s, manufacturing products was often done through the use of hand tools or basic machines in people’s homes. From the 18th to 19th centuries industrialization marked a shift to powered, specialty machinery, factories and mass production, all of which are used today to help with the processing of renewables.

People use energy a lot, especially these energy's coal and wind. Do you know a lot about the 2 energies? Their used to be a Windmill that makes water but now they invented Wind Turbines for electricity. Coal is also called dirty energy and 27 states mine

The United States of America produces energy using every resource available. There are nonrenewable, renewable, and other energy resources being used. Nonrenewable resources such as coal, oil, and natural gas are created by fossil fuels over a hundred of million years ago. Hydroelectric, solar, biomass, geothermal and wind power are considered renewable resources as they can be constantly replenished in a short period of time. Nuclear energy is in debate whether to be renewable or nonrenewable as it uses nuclear fission and nuclear fusion to create energy. This can come from any atom that makes up the world; however, right now nuclear energy is mostly using uranium which leads people to say this is nonrenewable.

The existence of our world and everything within depends on the ability of humans to harness and manipulate energy. It all began with the first ever discovery of heat energy in its primal state, fire. The Homo erectus were the first ever human species to discover, control and utilize the fire. This control of heat energy in form of fire was a turning point in the cultural aspect of human evolution that allowed them to cook food and obtain warmth and protection. Even today energy is vital to human existence, powering our transports, being utilized in creating structures that power our home and protect us and lighting our homes. But the real question here is to think what energy really is and why is it crucial to us. In attempt to answer these

The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could

In 1831, scientist Michael Farday discovered the first form of electricity. He found that when a magnet moved inside a copper coil it created what is known as an electric current. This invention is known as a turbine generator. Even today, in full sized power stations this simple invention is still used and works very effectively. These power stations create mass amounts of energy to turn the turbines. Most of the time the energy is made from the heat, for example when coal is burned. More environmentally friendly power stations use wind or flowing water to turn these turbines. This is known as renewable energy because it will not run out, unlike when oil and coal are used.(3)

It is a source of energy used in this modern society, it is widely use all over the word for different purposes.

The energy can neither be created nor be destroyed but it can be converted from one form to another. Electrical energy is widely used in day to day life in various applications. The generation of as electrical energy is nothing but the conversion of various other forms of energy into electrical energy. This generated energy is demanded by the consumers. There are three main parts of power system network: Generation, Transmission and Distribution.
